TL;DR: In this article, the authors presented two new soil damping formulations implemented in nonlinear one-dimensional site response analysis for small and large strains, which were used separately and simultaneously in non-linear site response analyses.

TL;DR: A review of advances in the field of non-linear site response analysis with a focus on 1-D site response analyses commonly used in engineering practice can be found in this paper.

TL;DR: In this paper, the authors extended the PSHA-NL procedure to incorporate a finite-fault model capable of generating near-source motions instead of using point-source models only, better approximate the range of available attenuation relations for the Central and Eastern United States (CEUS), and examine the hazard at very high levels of shaking.

TL;DR: In this article, four centrifuge tests supplemented by calibrated numerical simulations were performed to evaluate passive wedge formation and limiting lateral pressures imposed on a large, stiff foundation, and the results showed that the passive wedge was able to resist lateral pressure.

TL;DR: In this paper, a free-field lateral spreading centrifuge test is used to predict another free field lateral spreading test using the same soil profile but different input acceleration time history, demonstrating that even in a large strain problem, small strain damping plays an important role in numerical simulation results; it also shows the need to have pressure dependent dilation parameters in the employed soil constitutive model implemented in order to simultaneously reproduce measurements of pore water pressure, acceleration and lateral displacement.
